• 梯形：加速度、恒速、减速度
• 三角形：加速度、减速度
• 自定义多个分段：根据需要创建运动曲线分段，并分别进行定义。

末端固定是一种用于支撑滚珠丝杠组件末端的轴承配置。此处展示了3中常见的末端固定配置选项。固定加自由的组合方式支撑较少，而固定加固定的组合方式支撑较多。末端固定可影响丝杠的最大RPM和屈曲负载。

运动曲线分为三个等时间段或等距离段（加速度、恒速、减速度）。更多自定义选项，可查看多分段运动曲线选项。”

Changing the orientation of the linear unit affects which axes gravity acts upon. All available linear units can be mounted in any orientation.

Each linear unit has a specification for how much load it can support along each of its 3 axes. By entering in the total mass that needs to be moved, and the distances of the center of mass from the carriage, a resultant load for each axis is calculated.

In some cases, a linear unit can be used only to provide axis thrust on a mass. The weight of the mass being moved would then be supported by separate guide (such as a profile rail). In most cases, however, the weight of the mass is supported by the carriage of the linear unit itself.

Some linear units are available with 2 carriages. Adding a second carriage spreads the load out across a wider area, allowing the unit to support higher total loads. The unit will also support much higher moment loads along the Y-axis. The overall length of the unit will be longer for a given stroke length on a double carriage unit

Enter in the distance (in the X-axis direction) of the center of mass of the object being moved.

Enter in the distance (in the Y-axis direction) of the center of mass of the object being moved.

Enter in the distance (in the Z-axis direction) of the center of mass of the object being moved.

In some cases, in addition to the force of gravity while moving an object, external forces or moments will impact the carriage. Use the external forces section to enter in any additional forces or moments applied to the linear unit.
